$100nl: I squeeze with KK, flop brings an ace

[netstorm]

Villain is 23/10/2 over ~130 hands. We haven't had a lot of history postflop. I had been fairly active on this table, showing a lot of PF aggression.

How is my line? If I cbet here he will fold basically anything I beat, but by checking to him he might take a stab at the pot. Is this fine? Or do I c/f or b/f here?
